ABSTRACT
Surgical ciliated cysts are rare benign cystic lesions that generally occur a number of years after invasive surgical procedures or trauma involving the maxilla. The appearance of this cyst after orthognathic surgery is a complication that has rarely been reported. It usually shows as a well-defined radiolucency in the maxilla in young adults mimicking other maxillary cysts. Therefore, an exhaustive clinical-radiological diagnosis is needed to establish its differential diagnosis and appropriate treatment. The present study describes the case of a surgical ciliated cyst that appeared 20 years after LeFort I orthognathic surgery. Treatment consisted of complete enucleation with primary closure and removal of osteosynthesis material. Histopathological examination confirmed the diagnosis of a maxillary cyst lined with pseudostratified ciliated columnar cells. Clinicians should be aware of this rare type of cyst in patients with a history of maxillary surgery or trauma to establish a differential diagnosis and ensure appropriate management.
ABSTRACT
Pigmented villonodular synovitis is a benign pathology with locally aggressive behavior caused by an uncontrolled proliferation of the articular synovial membranes. Here the authors present a case of pigmented villonodular synovitis of the temporomandibular joint with middle cranial fossa extension and review the different management options including surgery, which have been proposed to target this condition in the recent literature.
